MainWP Code Snippets Extension

MainWP Code Snippets Extension is an official MainWP tool designed for administrators of multiple WordPress sites who need to manage PHP code snippets from a centralized location. This extension eliminates the need to manually edit the theme's functions.php file or the wp-config.php of each child site, allowing you to run, modify, and query code from the main MainWP Dashboard panel.

The extension offers three code snippet execution modes. The first allows you to run functions directly on child sites, ideal for applying real changes such as customizing the admin footer or syncing plugin settings. The second mode retrieves information from child sites, such as the number of published posts or any queryable data, displaying it in the panel output. The third mode modifies the wp-config.php file of child sites, allowing you to increase the WordPress memory limit, block external requests, disable WP-Cron, and apply other critical configuration constants.

Among its main benefits, it stands out the ability to save and reuse the most used code snippets, saving time when applying the same snippet to multiple sites. It also allows you to run code on several child sites simultaneously, streamlining the maintenance of large WordPress networks. Users can disable theme and plugin editors, block core updates, adjust autosave intervals, and protect sites against malicious URL requests, all from one place.

This tool is aimed at advanced users and developers with PHP experience, as the executed code is the user's own responsibility. It works as mini-plugins that extend the functionality of child sites without adding extra load, helping to clean the trash, update settings, create redirects, and optimize the overall performance of the site network.

With MainWP Code Snippets Extension, custom code management becomes an efficient, secure, and centralized process, allowing administrators to maintain full control over their WordPress sites without needing to access each one individually.
